Which to buy?

So the wife says she wants a shotgun now. She wants something simple and I am at a loss. She likes coach guns, but also like over-unders. So It's between those I'm just debating what gauge to get them in.

She is 5'3" and 115 lbs. Do I just do 12 gauge with reduced recoil rounds or do I step it down to a 20 gauge? My issue is I am likely going to be shooting it too maybe to lower the clay pigeon population and maybe the pheasant population a little bit.

So side-by-side or over-under and what gauge? It's going to be hers, but you know the old addage "What's hers is mine and what's mine is ours."

Never thought of the 16 ga. I might have to look into that. She got all into it when the chick in Georgia shot a home invader 5 times and he walked out and drove away. She wants a "Definite" and not a "Maybe" lol

I'll tell ya,, it's awfull hard to beat the real "sweat 16",, the model ,, had one and ,,,STUPIDLY ,,,,, sold it,,, real dumb. That thing swung so nice, pointed so naturally, easy recoil, and just plain knocked down birds and rabbits!! It was very nice. One of my buds has a over/ under Weatherby 20 ga that is nice as Hell too,, don't remember the model though? That handled extremely well too.

There are some higher end models still made. Most are quite expensive though.

I've heard remington and browning still make them, but can't confirm if that is true or not.
